Hi everyone! I just bought a halfmoon betta last week named Finnegan! I noticed that when I bought my betta, his tail was a little ripped towards the top corner, which I assumed to be from neglect of care during its time at Petco. I was just wondering, besides keeping the water clean... What are some things I can do to help the fin regrow? Are there any foods or medicine out there for fin regrowth?

Some info about Finnegan's living situation:
He lives alone in a 5 gal tank w/ filter (although keep it off most of the time).
water conditioner: Prime
water change plans: 50% every 4 days

The filter doesn't do its job if it is not on all the time ( it can be turned off for a little bit during maintenance and moving). If the current is too strong, then you can baffle the filter with a plastic bottle or a sponge, there are various threads on how to do it. I know that in my brother's 5gal, it was too strong so we baffled it and it worked just fine!

yeah bettas prefer still waters but a filter is still recommended to maintain water quality. What kind of filter do you have? internal power filters can be waaay too strong for bettas but some of them you can adjust the flow rate. I used box/corner filters and I know a lot of people on here use sponge filters.

About 6 months ago I got a betta that had no fins. Petsmart gave him to me. It wasn't fin rot. Some people said it looked like he'd bitten them off. I was told to put him in clean, warm water with some stresscoat and a bit of salt. Within a few weeks the transformation was remarkable. He had regrowth and was such a beautiful fish. I bated to have to give him up when I moved. He's the one in my avatar.
